Sprint 215 Plan: Language-First Efficiency Auto-Reroute

Goal

Automatically reroute low-yield language-first executions to deterministic paths.

Steps

• Step 2114: Add low-yield detector into A/B orchestration runtime.
• Step 2115: Implement auto-reroute to AST-first when threshold exceeded.
• Step 2116: Add reroute trace packet and token-savings report.
• Step 2117: Add strict fail-fast mode for repeated low-yield runs.
• Step 2118: Add Sprint215IntegrationSummary.h.
